o Major features:
- Increase the base amount of time that a canonical connection
- (one that we have made to a known OR) is allowed to stay open
- from a 3 minutes to 15 minutes. This leaks less information
+ (one that we have made to a known OR) is allowed to stay idle
+ from 3 minutes to 15 minutes. This leaks less information
about when circuits have closed, and avoids unnecessary overhead
from renegotiating connections. Part of a fix for ticket 6799.
- Base connection idleness tests on the actual time elapsed since
the connection last had circuits, not on the time when we last
- added non-padding. This also makes it harder to tell when the last
- circuit closed by looking at when a connection closes. Part of a
- fix for ticket 6799.
